May 22, 2015: One of Clinton’s emails is revealed to contain classified information; Clinton says she is not concerned.

Out of the first batch of Clinton’s over 30,000 emails made public on this day, one is classified, and at the “secret” level, which is the middle classification level. This shows that at least some of Clinton’s emails contain classified information, especially since only a small batch of 296 emails are released on this day.

Asked if she is concerned that such information was stored on her private server, Clinton simply says, “No.” She also says it “doesn’t change the fact all of the information in the emails was handled appropriately.” (The Associated Press, 5/22/2015)
